Re: How to run multiple RadosGW instances under the same zone

[Ben Hines <bhines@xxxxxxxxx>]

It works fine. The federated config reference is not related to running multiple instances on the same zone.

Just set up 2 radosgws give each instance the exact same configuration. (I use different client names in ceph.conf, but i bet it would work even if the client names were identical)

Official documentation on this very common use case would be a good idea, i also figured this out on my own.

Hello Srinivas,

Yes, we can use Haproxy as a frontend. But the precondition is multi RadosGW instances sharing
the SAME CEPH POOLS are running. I only want the master zone keep one copy of all data. I want
to access the data through ANY radosgw instance.
And it said in http://docs.ceph.com/docs/master/radosgw/federated-config/
"zones may have more than one Ceph Object Gateway instance per zone.". So I need the official way
to set up these radosgw instances.

thx

Hi Joseph,

 

You can try haproxy as proxy for load balancing and failover.

 

Thanks,

Subject: How to run multiple RadosGW instances under the same zone

 

Hello,

How to run multiple RadosGW instances under the same zone?

Assume there are two hosts HOST_1 and HOST2. I want to run

two RadosGW instances on these two hosts for my zone ZONE_MULI.

So, when one of the radosgw instance is down, I can still access the zone.

There are some questions:

1. How many ceph users should I create?

2. How many rados users should I create?

3. How to set ZONE_MULI's access_key/secret_key?

4. How to set the 'host' section in the ceph conf file for these two 

   radosgw instances?

5. How to start the instances?

    # radosgw --cluster My_Cluster -n ?_which_rados_user_?

I read http://docs.ceph.com/docs/master/radosgw/federated-config/, but

there seems no explanation.

Your answer is appreciated!

thx

Joseph
